Researchers at Kaiser Permanente have discovered new evidence that strengthens the link between chemical bisphenol A, or BPA, and childhood obesity, at least in girls.
The researchers studied the urine samples of more than 1,300 children in China and compared them with their weight. The children were also asked about the amount of junk food, fruits and vegetables that they eat, the amount of time they exercised, how long they play videogames every day and whether their parents were overweight.
AdvertisementThe researchers found that girls between 9 and 12 years old who had higher levels of BPA in the samples were twice as likely to be obese compared to girls who had average or below average levels of BPA. The researchers were unable to find a similar link in older girls or among boys. The study has been published in the journal PLOS One.
